Abstract

The utility model relates to a controlling mechanism for the tool-holder movement of a spring-winding machine, which is composed of a cam, a swing arm and a crank which are respectively arranged on a cam shaft, an upper and middle shaft and an upper shaft and a double crank connection rod mechanism which is used for connecting the upper shaft and other shafts. When the utility model is used, a head stopping screw of the relevant crank is only needed to fasten and release. A-shaped cam can respectively control an upper and middle tool bar and a lower and middle tool bar. A distance adjustment cam and a cutting cam can also respectively control an upper tool bar and a lower tool bar. In such a way, the upper and middle tool bar and the lower and middle tool bar can be taken as a controllable shaped tool as well as a shaped tool. The upper tool rod and the lower tool rod can be taken as a distance adjustment tool as well as a cutting tool. Consequently, the utility model can make the spring-winding machine have two functions that the spring can be winded from left and right.
